Abstract
The utility model discloses a double-clip type manual butterfly valve. The double-clip type manual butterfly valve comprises a valve body and a butterfly valve seat, wherein the valve body and a connecting rod of the butterfly valve seat are detachably connected through a screw, a positioning boss is arranged on the butterfly valve seat and arranged opposite to the end, connected with the valve body, of the butterfly valve seat, and the cross section of the end, close to the valve body, of the connecting rod is in the shape of a regular hexagon. The double-clip type manual butterfly valve has the advantages that the positioning boss is arranged on the butterfly valve seat to play a role in positioning so that installation can be convenient, and the butterfly valve seat can be prevented from twisting when water pressure is overhigh; the width of the positioning boss ranges from 25 mm to 35 mm, the thickness of the positioning boss ranges from 10 mm to 20 mm, the positioning boss can be well installed on the component, and the effect is remarkable; due to the fact that the cross section of the end, close to the valve body, of the connecting rod is designed to be in the shape of a regular hexagon, the butterfly valve seat is firmly fixed and does not rotate, installation is convenient, the procedure is simplified, and the double-clip type manual butterfly valve is easy and convenient to use.
Description
Technical field
The utility model relates to butterfly valve field, particularly a kind of wafer type Hand-operated butterfly valve.
Background technique
the butterfly plate of wafer type Hand-operated butterfly valve is installed on the diametric(al) of pipeline, and in butterfly valve body cylindrical channel, disc butterfly plate rotates around axis, angle of swing is between 0 °-90 °, can play the effect of Flow-rate adjustment, in the time that butterfly plate rotates to 90 °, valve reaches maximum opening.Wafer type butterfly valve structure is simple, volume is little, lightweight, only formed by a few parts.And only need half-twist to get final product fast opening and closing, simple to operate, this valve has good fluid control characteristic simultaneously.Existing wafer type Hand-operated butterfly valve is installed owing to being difficult to precise positioning, therefore brings some inconvenience to installation, and in the time that hydraulic pressure is excessive, butterfly valve easily twists, and butterfly valve using effect is reduced greatly simultaneously, and the life-span of easy loss butterfly valve, causes very large inconvenience.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of wafer type Hand-operated butterfly valve, can precise positioning, and can fixedly secure.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
A kind of wafer type Hand-operated butterfly valve, is characterized in that, comprise valve body and butterfly valve seat, described valve body is removably connected by screw with the connecting rod of butterfly valve seat, on described butterfly valve seat, just the one end that connects valve body is provided with to positioning boss; Described connecting rod is regular polygon near the cross section of valve body one end.
A kind of wafer type Hand-operated butterfly valve, is characterized in that, described connecting rod is regular hexagon or regular pentagon near the cross section of valve body one end.
A kind of wafer type Hand-operated butterfly valve, is characterized in that, the width of described positioning boss is 25-35mm, and thickness is 10-20mm.
A kind of wafer type Hand-operated butterfly valve, is characterized in that, the width of described positioning boss is 30mm, and thickness is 15mm.
A kind of wafer type Hand-operated butterfly valve, is characterized in that, on described connecting rod, cross section is that an orthohexagonal segment length is 1/4 ~ 3/4 of whole connecting rod length.
A kind of wafer type Hand-operated butterfly valve, is characterized in that, on described connecting rod, cross section is that an orthohexagonal segment length is 1/2 of whole connecting rod length.
Usefulness of the present utility model is: 1. on butterfly valve seat, be provided with positioning boss, play the role of positioning, make easy for installation, in the time that hydraulic pressure is excessive, can prevent that it from twisting, the width of described positioning boss is 25-35mm, thickness is 10-20mm, can be better and parts install, effect is remarkable; 2. connecting rod, near the cross section of valve body one end for regular hexagon designs, can make butterfly valve seat firmly fixing, do not rotate, and easy for installation, simplify procedures, easy to use.
Brief description of the drawings
